如何在C++中包含外部库

我正在尝试将一个名为SVL（简单向量库）的外部库包含到c++中。我在这方面遇到了很多麻烦。我使用的是Mac OSX，库的README只有适用于Windows的教程。

我做了

 make clean
 make  

这创建了库文件libsvl.a和libsvl.dbg.a。我看到，在文件的README中，它说要将其作为svl/vec3.h包括在内，大约用于不同的头。但当我尝试这样做时，它不起作用，仍然说，

vertex.hh:9:10: fatal error: 'svl/Vec3.h' file not found
#include <svl/Vec3.h>
     ^
1 error generated.
vertex.cc:10:10: fatal error: 'svl/Vec3.h' file not found
#include <svl/Vec3.h>  

你能告诉我我缺了什么吗？我可能需要更好地定义通往图书馆的道路，或者做一些不同的事情。

库文件与其他代码的相对路径为../svl-1.5/lib/libsvl.a

使配置文件

#

CONFIG = OSX
# --- Compilation
----------------------------------------------------------
CC          =   cc
CXX         =   c++
LD          =   c++
MAKEDEP     =   c++ -MM $(SYS_INC_DIRS) $(INC_DIRS) $(SRCS) >     Makefile.depend
CPP         =   cpp
LIBTOOL     =   glibtool

DEST        =   $(REACTOR)
config:
    @echo "configured for Mac OSX"

SYS_INC_DIRS        =  -I/sw/include

CL_EXT_FLAGS = -DCL_TMPL_INST -DCL_HAS_VSNPRINTF -DCL_POSIX_TIME
VL_EXT_FLAGS = -DVL_HAS_ABSF -DVL_USE_MEMCPY

运行make 的结果

cd src && /Applications/Xcode.app/Contents/Developer/usr/bin/make REACTOR=..
c++  -O2   
            -c LibSVL.cpp -I../include -I/sw/include

            -c Basics.cpp -I../include -I/sw/include
ar rcu libsvl.a LibSVL.o Basics.o
mkdir -p ../lib
mv libsvl.a ../lib
c++ -DDEBUG  -g  
            -DVL_DEBUG 
            -c LibSVL.cpp -o LibSVL.do -I../include -I/sw/include
c++ -DDEBUG  -g  
            -DVL_DEBUG 
            -c Basics.cpp -o Basics.do -I../include -I/sw/include

完成make文件
